Specification of Letters Patent.

Application filed June 17, 1912.

SerialNo. 704,087.

To all whom it may concern: g

- Be it known that I, Anornn CixurnnLL, a citizen of the United States, residing in Chicage, in the county of Cook and 'State'of Illinois, have invented a new and useful 1mprovement in Ballast-Dumping Cars, of which the following is a specification.

This improvement relates to dump ,cars, and more particularly to that type used for ballasting, the rail track.

As is well known, it is customary to ballast a rail track by filling a car with ballast opening and closing each of the four sets of I doors, although, as will be obvious to those skilled in the art, other arrangements of door operating mechanisms can be used.

lvl y invention furthermore consists in the improvements in the parts and devices and in the novel combinations of parts and devices herein shown, described or claimed.

In the drawings forming a part of this specification, l igurc 1 is a partial plan view of a car embodying my imprm'cment's. Fig. 2 a side elevation of the car shown in Fig. 1. Fig. 3 is a transverse, vertical section, taken substantially on the line 33 of Fig. 2 and being upon a somewhat enlarged scale, one shiftable partition being shown ina vertical osition against the side ofv the car and anothliir partition in full in the hopper at the left hand side of the car and in dotted lines in two positions in the hopper at the right hand side of the car, and Fig. 4 is a plan view of the door operating mechanism, parts being broken away in order not to crowd the drawing.

In the drawing, A denotes the body of a car, the same being provided with alongitudinally arranged I-beam center sill 10 and a plurality of longitudinally arranged hoppers 13. B on opposite sides of the center sill. Each of the hoppers B is provided with a pair of door openings C C at the lower end thereof, and hinged doors 11 for each of said openings, each of the doors 11 being preferably hinged at its upper edge to suitable hinge brackets 12, 12, secured to the upper, outer side sheets of the hoppers and the center sill of the car (see Fig.

Arranged longitudinally of the car and centrally thereof is an operating shaft 13 which preferably extends throughout the length of the hoppers in order to operate the entire set of doors, said shaft as shown in Fig. 4, being provided with a worm gear 14 at one end thereof, the same being adapted' to be rotated by means of a worm 15 secured to the end of a transversely arranged shaft 16, the latter being preferably proided at its outer end with a hand wheel 17. The worm 15 and worm gear 14 will serve to automatically lock the operating shaft in any position to which it may be turned whereby the amounts to which the doors are opened may be regulated and adjusted to thereby regulate the flow of material from the car through the openings.

Suitable connections for operating each of the doors are provided, the same, as shown in Figs. 3 and 4, consisting of short links 18, 18 for the inner set of doors 11 and elongated links 19, 19 for operating the outer sets of doors.

Each of the hoppers B at its lower end is provided with an upwardly pointed wedge shaped member 20, located centrally above the track rails 21, Q1.

\l'ith the door operating mechanism which have shown, it will be obvious that all of the doors 11 are operated simultaneously, and hence, unless some means is provided to prevent it. four streams of material or ballest will always be allowed to flow from the hoppers to the track below, but inasmuch as it is not always desirable to allow the ballast to drop in this manner, I provide suitable means adapted to cover any of the door openings C, C of the hoppers, and said means preferably consist of shiftable partitions D, which may be composed of a plurality of loose boards, said partitions D being so proportioned and arranged that they extend the entire length of each hopper the one case, as shown in section in the hop- I per at the left hand side of Fig. 3, or from a .also made such that the shiftable partitions needed. Whenever D may extend across the top of the hoppers as shown indotted lines in the hopper at the right hantf'sidewf 3, in which case the partitions are supported by angle braces 23, 23 to form a flooring for the-car and thus cut out the hoppers when the latter are not it is desired to allow ballast to flow from the hoppers, the shiftable partitions D may conveniently be retained in position against the sides of the car by retaining members 25, as shown in full in Fig. 3 at the right hand side thereof. 1

From the foregoing description, it will be seen that the shiftable partitions or door covers cooperate with the door operating mechanism which I have shown to make a car which may be adapted to drop ballast or other materials to. the outsides of the rails only or to the insides of the rails only, or to points one'inside one rail and outside of the other rail, or to cut out the hoppers entirely.

Various changes and modifications may be made in the details of construction without departing'frorn the spirit of the invention, and such changes and modifications are contemplated as fall Within the scope of the claims appended hereto.

1. In a car of the class described, in combination, a car provided withhoppers arranged on opposite sides of the longitudinal center of the car, apair of hinged side doors, a pair of hinged center doors and a longitudinally arranged operatin shaft, and separate connections from said shaft directly to each of the doors, whereby all the doors-areadapted to be positively opened and closed from said shaft.

2. In a car of the class described, in combination, two sets of doors, one set on each side of the center sill and each set comprising a pair of oppositely swinging doors, an operating shaft and separate connections from the Operating shaft directly to each of the doors for positively opening and closing the same. i I

3. In a car of the class described, in combination, a hopper provided with a pair'of door openings, a hinged door for each of said 'openings, echanism for operating the doors and shiftable means for covering one of said openings to thereby prevent escape of material thcrethrough. but at the same and shiftable means said openings to thereby prevent escape of all of the'openings of vided with a time allow material to pass through another bination, a hopper provided with door openings, hinged doors for each of said openings, mechanism for operating the doors for covering one of material therethrough, but at the same time allow material to pass through another opening of the hopper, said means comprising a partitionadapt-ed to be positioned over the top of the hopper and form part of the-floor of the car when the hopper is not in use.

5. In a car of the class described, in combination, a hopper provided with door openings, hinged doors for each of said openings, mechanism for operating the doors, and a removable and detachable partition adapted to cover one of the openings in the hopper to prevent escapemept of material therethrough, but at the same time to allow material to pass through another opening of the hopper, and means for retaining the partition in place.
